Facebook is revamping its Web site with several new features that give users more information about their networks in real time. The changes have been widely compared to the updates people send and get via microblogging site Twitter, which Facebook apparently now views as one of its competitors. The new site allows friends’ posts to be streamed in real time. Changes you make are updated instantly on friends’ home pages as well, which are now called “profiles.” Other changes gives users more control over what they see.
